Abstract: PURPOSE: A signal generation method used to an optical disk generator reproducing a data recorded in optical disk by using optical beam(spot) scanning a guide groove and a land provided on the optical disk, and detects a tracking error signal designating a spot position of optical beam provided in the optical disk, and detects a cross track signal leading 90°C about the tracking error signal. CONSTITUTION: A cross track signal calculation method detects a main spot at an optical detector. A first side spot is detected from the divided optical detector. A second side spot is detected by the divided optical detector(671,672,673). A first error is calculated as an error in direction of a radius of the optical disk from the 4 detection signals detected by the optical detector. A second error is calculated as an error of two detection signals of the optical detector. The third error is calculated as an error of two detection signals of the third optical detector. A tracking error signal is calculated by subtracting the sum of the second and third errors from the first error. A difference between the second and third errors is calculated. a tracking error signal TE and a cross track signal shifted by 90°C are calculated.
